I asked the question given in the link below but no replies have
appeared so far. So it is time to fire again ;-)
I was processing Ansys generated mesh structures in gmsh. There are two
questions from my side, the questions are in the above link. However, my
question on partitioning is somewhat more urgent now so here that comes,
I am writing the input mesh file in a mixed order(there is also an
example file attached to the above link) since Ansys optimizes the mesh
structure for the the bandwidth of the resulting matrices. If I write
the elements in different order than a consecutive order, say [1: nelm
], I guess gmsh wrappers for the partitioners are not that smart yet to
recognize this difference or I have a conceptual misunderstanding.
Because giving the input file to gmsh with this mixed order screws up
everything after the partitioning operation, however sorting the
elements to be in a consecutive order solves the problem. I wanted to
confirm that this is the right way for me to follow, I found this by
some reasoning and trials.
Any comments are appreciated, best wishes for all.
